Augmenting progress on the elimination of vertical transmissions of HIV in India: Insights from Spectrum-based HIV burden estimations.

The government of India has adopted the elimination of vertical transmission of HIV as one of the five high-level goals under phase V of the National AIDS and STD Control Programme (NACP). In this paper, we present the data from HIV estimations 2021 for India and select States detailing the progress as well as the attributable causes for vertical transmissions. The NACP spearheads work on mathematical modelling to estimate HIV burden based on the periodically conducted sentinel surveillance for guiding program implementation and policymaking. Using the results of the latest round of HIV Estimations in 2021, we analysed the mother-to-child transmission (MTCT) during the perinatal and postnatal (breastfeeding) period. In 2021, overall, around 5,000 [3,000-7,800] vertical transmissions were estimated nationally with 58% being perinatal infections and remaining during breastfeeding. MTCT at 6 weeks was around 12.95% [9.45-16.02] with the final transmission rate at 24.25% [18.50-29.50]. Overall, 57% of vertical transmissions were among HIV-positive mothers who did not receive ART during pregnancy or breastfeeding, 19% among mothers who dropped off ART during pregnancy or delivery, and 18% among mothers who were infected during pregnancy or breastfeeding. There were significant variations between States. Depending upon the States, the programme needs to focus on the intervention domains of timely engagement in antenatal care-HIV testing-ART initiation as well as programme retention and adherence support. Equally important would be strengthening the strategic information to generate related evidence for inputting India and State-specific parameters improving the MTCT-related modelled estimates.

Assessment of effectiveness of targeted intervention program under national AIDS control program among injecting drug users across India.

Background: High HIV prevalence among injecting drug users (IDUs) remains a cause of concern and are considered key drivers of concentrated epidemic in India. The present paper aims to assess the effectiveness of the targeted intervention (TI) program on the risk behaviors among IDUs across regions of India. Materials and Methods: This paper used the data from the integrated biological and behavioral surveillance 2014-2015 among the IDUs in India. Descriptive statistics and propensity score matching analysis was carried out to understand the effectiveness of the TI program on the new needle/syringe used and needle/syringe shared in the last injecting episode by accounting for the covariates. Results: The matched samples estimate, i.e., average treatment effect on treated of new needles/syringe used and shared in the last injecting episode by those who received needles/syringes from peer educator or outreach workers (PE/ORWs) and those who did not receive was 2.8% (confidence interval [CI]: 0.05-5.6) increase in the use of new needles/syringes and 6.5% (CI: -9.7--3.3) decrease in the needles/syringes shared in last injecting episode indicating that IDUs who received new needles/syringes from PE/ORWs are more likely to use new needle/syringe and less likely to share needle/syringes to those who did not receive needles/syringes. The results vary across the different regions of India. Conclusion: TI program proves to be an effective initiative in the behavior change among IDUs as substantiated by use of new needles/syringes and decreased sharing of needles/syringes. TI program coverage varies from region to region and may further be expanded to accelerate the program services to prevent HIV/AIDS.

Analysis of a Targeted Intervention Programme on the Risk Behaviours of Injecting Drug Users in India: Evidence From the National Integrated Biological and Behavioural Surveillance Survey.

OBJECTIVES: This study provides insights on the impact of a targeted intervention (TI) programme on behaviour change among injecting drug users (IDUs) in India. METHODS: This paper examined the data from the Integrated Biological and Behavioural Surveillance 2014-2015 for IDUs in India. Logistic regression was performed to understand the factors (TI programme services) that affected injecting risk behaviours by adjusting for covariates. Propensity score matching was conducted to understand the impact of the TI programme on using new needles/syringes and sharing needles/syringes in the most recent injecting episode by accounting for the covariates that predicted receiving the intervention. RESULTS: Participants who received new needles and syringes from peer educators or outreach workers were 1.3 times (adjusted odds ratio, 1.29; 95% confidence interval [CI], 1.09 to 1.53) more likely to use new needles/syringes during most recent injecting episode than participants who did not receive needles/syringes. The matched-samples estimate (i.e., average treatment effect on treated) of using new needles in the most recent injecting episode showed a 2.8% (95% CI, 0.0 to 5.6) increase in the use of new needles and a 6.5% (95% CI, -9.7 to -3.3) decrease in needle sharing in the most recent injecting episode in participants who received new needles/syringes. There was a 2.2% (95% CI, -3.8 to -0.6) decrease in needle sharing in the most recent injecting episode among participants who were referred to other services (integrated counselling and testing centre, detox centres, etc.). CONCLUSIONS: The TI programme proved to be effective for behaviour change among IDUs, as substantiated by the use of new needles/syringes and sharing of needles/syringes.

Association of Variant rs7903146(c/t) Single Nucleotide Polymorphism of Transcription Factor 7-like 2 Gene with Newly Detected Hyperglycemia in Pregnancy.

Background: Transcription factor 7-like 2 (TCF7L2) gene has a significant role in hyperglycemia in pregnancy (HIP) risk. The current study was planned with the aim to evaluate the association of single nucleotide polymorphism (SNP) rs7903146 in patients of newly detected HIP among Indian population of northern region. Methods: This study was an observational case control study done among newly detected HIP (The World Health Organization (WHO) criteria, 2013) and healthy pregnant females without diabetes. Participants from both the group were genotyped for rs7903146 (C/T) variant of TCF7L2 gene using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) technique. Results: A total of 71 cases of newly detected HIP were included in the study, out of which 25 (35.2%) of them were of first-time detected diabetes mellitus in pregnancy (DIP) and 46 (64.7%) were of gestational diabetes (GDM) and 100 were pregnant females without diabetes in third trimester were enrolled as controls. Average age of participants in the case group was 28.7 ± 4.0 years and the control group were 26.5 ± 3.6 years (P value 0.09). The wild homozygous CC genotype, heterozygous CT genotype and homozygous TT genotype were present in 39.4%, 53.5%, 7.1% of case group vs 53%, 43% and 4% of control group, respectively. No significant association of rs7903146(C/T) SNP of TCF7L2 gene in HIP (CC/CT, CC/TT P value 0.15, 0.38, respectively) in our population was found. There was no significant difference in the distribution of genotypes between DIP and GDM. Conclusion: This study shows no evidence of association of rs7903146(C/T) SNP of TCF7L2 gene with newly detected HIP in our population.

The clinical demand and supply of blood in India: A National level estimation study.

BACKGROUND: Estimating the clinical demand for blood and components arising in a health facility is crucial to ensure timely availability of blood. This study aims to estimate disease-specific clinical demand, supply and utilization of whole blood and components in India. METHODS: We conducted a national level cross-sectional study in five randomly selected states from five regions of the country. We included 251 public and private facilities representing primary, secondary and tertiary care facilities. We collected annual disease-specific demand, supply and utilization of blood and components using a structured tool. We estimated the national demand by extrapolating the study data (demand and beds) to the total number of estimated beds in the country. FINDINGS: According to the study, the total clinical demand of 251 health facilities with 51,562 beds was 474,627 whole blood units. Based on this, the clinical demand for India was estimated at 14·6 million whole blood units (95 CI: 14·59-14·62), an equivalent of 36·3 donations per 1,000 eligible populations, which will address whole blood and component requirement. The medicine specialty accounted for 6·0 million units (41·2%), followed by surgery 4·1 million (27·9%), obstetrics and gynecology 3·3 million (22·4%) and pediatrics 1·2 million (8·5%) units. The supply was 93% which is equivalent to 33·8 donations against the demand. CONCLUSION: The study indicated a demand and supply gap of 2.5 donations per 1,000 eligible persons which is around one million units. The gap emphasises the need for sustained and concerted efforts from all stakeholders and for increasing the awareness about repeat voluntary non-remunerated blood donation (VNRBD); optimizing the availability of blood components through efficient blood component separation units; promoting modern principles of patient blood management and strengthening capacities of human resources in the blood transfusion system in India.

A review of legal, regulatory, and policy aspects of blood transfusion services in India: Issues, challenges, and opportunities.

BACKGROUND: Blood transfusion services (BTS) in India have progressed significantly during the last three decades. However, there is still inequity in the availability and access to blood due to various demand and supply-side issues. Appropriate laws, regulations, policies, and guidelines are critical to ensure universal access to blood. AIMS AND OBJECTIVES: This article aims to review the evolution and current status of legal, regulatory, and policy framework and analyses the issues, challenges, and opportunities for improvement of BTS in India. METHODS: This article is based on an extensive review of currently available literature and government documents. RESULTS: The review highlights the gaps and challenges in terms of licensing, safety and quality, voluntary blood donations, the organization of BTS, access to services, and regulatory bodies. The findings emphasize the need for a coordinated response by either the National Blood Transfusion Council or a newly established autonomous "National Blood Authority" consisting of technical, administrative, and legal experts which must be exclusively responsible for regulating the BTS. As adherence to quality management systems in blood banks is not a mandatory requirement, it recommends a legal measure to ensure mandatory quality assurance in blood banks and storage centers. Towards ensuring efficiency and universal access to blood, this article recommends evidence-based criteria for establishing new blood banks to avoid skewed distribution of blood banks, component separation facilities, and blood storage centers. CONCLUSION: The review emphasizes the need for periodic reviews and updates of the legal, regulatory and policy framework, considering the rapid developments and technical advancements with increasingly complex systems and processes in transfusion medicine.

Clinical Profile and Outcome of Pregnant Patients with Acute HEV Hepatitis During Water Borne Epidemic in Himachal Pradesh: A Hospital Based Study.

Background: Recent outbreak of HEV hepatitis epidemic in Himachal Pradesh in Shimla caused significant morbidity and mortality especially among pregnant patients. Overall mortality is 0.5- 4% in patients developing acute hepatic failure (ALF) and is significantly higher in pregnant patients (20%). Present study conducted to observe clinical profile and outcome in pregnant patients. Methodology: this is a retrospective observational study done on admitted pregnant and post partum patients with acute HEV hepatitis during 3 months periods. History focussing on symptoms, duration, onset, progression, co morbidities, pregnancy outcome, complications noted. Confirmation of the HEV infection was done using HEV IgM ELISA. Results: Total 26 patients observed, among which 8 were pregnant and 18 were post partum Average age of presentation was 26.11±3.7 years and average duration of hospital stay 10.46 days. 8 (30.76%) patients required ICU care Presenting complaints were similar to typical presentation in viral hepatitis. All patients were icteric at presentation and 8 (30.76%) patients had hepatic encephalopathy (HE) and 8 (30.76%) patients had ALF, 20 (76.92%) sepsis and 7(26.92%) underwent preterm labour. Out of the total 14 patients who delivered, poor fetal outcome was seen in 5 patients died during this period (15.38%). Factors responsible for in hospital mortality were altered mental status at presentation (p0.018), edema (p 0.046), HE(0.018), acute liver failure(0.018). Conclusion: HEV infection has more morbidity and mortality among pregnant females and poor fetal outcome. Mortality is high (15.38%). Altered mental status at presentation, edema, HE, ALF have significant correlation (<0.05) with the mortality.
